Executive summary:

The density at of the substance Hydrocarbons, C16-C20, n-alkanes, isoalkanes, <2% aromatics, measured at 20°C following the ASTM D 7042-04 method, is 0.782 g/cm3.

Description of key information

There is no data available for Hydrocarbons, C14-C20 (even numbered), n-alkanes, isoalkanes, <2% aromatics.However, data is available for structural analogue, Hydrocarbons, C16-C20, n-alkanes, isoalkanes, <2% aromatics. This data is read across to based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.

The density of the substance "Hydrocarbons, C16-C20, n-alkanes, isoalkanes, <2% aromatics", measured following the ASTM D 7042-04 method, is 0.782 g/cm3 at 20°C.

Key value for chemical safety assessment

Relative density at 20C:
0.782
